During this year's Ultra Music Festival in Miami, 28-year-old Erica Mack was trampled by gate crashers while working as a security guard. As a result, Miami Mayor Tomás Regalado and other city officials have called for an end to the festival. Today, the festival has issued a statement promising a comprehensive review of their security measures.

Consistent with our commitment to improve every year, ULTRA is conducting a top to bottom review of security procedures and measures to assess where we can add even more security for the event next year. This review will include an assessment with the Miami Police Department of how security can be enhanced immediately outside our gates to prevent a criminal incident of this nature from happening again.

They note that Mack is receiving treatment at Jackson Memorial Hospital and say that her condition is improving. "ULTRA condemns these criminal acts that resulted in her injury," they write.

According to the statement, this year's festival had 257 police officers per day (49 more per day than last year), 18 undercover officers, 28 additional officers per day on the perimeter and inside the event, and 12 bike details. Double fencing and an eight-foot, high-level security fence surrounded around the entire venue.
